IMPROVEMENT IN CARDING-ENGINES.

Specification forming part of Letters Patent No. 33,972, dated December 17, 1861.

To aZZ whom it may concern:

Be it known that I, JOSEPH DAVIS, of East Vilton, in the county of Hillsborough and State of New Hampshire, have invented a new and useful Improvement in the Oarding- Engine; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a side elevation,`Fig. 2 a longitudinal section, and Fig. 3 a transverse section, of the main card-cylinder and the frame of a common carding-engine for carding wool, the workers and strippers, feedingapron and licher-in, and top cards thereof not being exhibited, the application of my invention being directly to the main card-cyl inder.

The nature of my invention consists in an arrangement and combination or application of an endless traversing apron or grid (or its mechanical equivalent) with the main cardcylinder of a carding-engine, the said grid or apron being made to operate in such manner while the carding-machine is at work as to receive the waste wool or fibrous material or extraneous matters that may fall or be thrown thereon from the lower part of the said cylinder, and not only convey such fibrous material back to the cylinder or into a position to enable such cylinder to again seize such fibrous material, but discharge the dirt, or more or less of it, that may fall upon the said apron or grid.

My invention further consists in an arrangement and combination of an adjustable supporter or its equivalent with the endless apron or grid and the main card-cylinder of the carding-engine, the said adjustable supporter being for the purpose not only of preventing improper vibration of the apron or grid with respect to the card-cylinder, but for regulating the distance of the apron or grid from the cylinder, as circumstances may require.

It is well known that during the operation of a carding-engine, and particularly while it is employed in carding wool, much of the wool is thrown or discharged from the lower part of the main card-cylinder, which generally makes about one hundred revolutions Vmain card-cylinder.

per minute. The wool so expelled has been termed waste. This loss or waste per day on an ordinary carding-engine amounts to about two pounds, which in the state of waste is only worth about one-twelfth the Value of the same weight of wool that may be on the cylinder. By my invention this waste, or a large portion of it, is automatically saved and reincorporated with the wool on the main card-cylinder, and thus it has its original value restored.

My invention not only effects to the manufacturer the saving above mentioned, but by preventing the accumulation and storage of waste lessens the risk of nre arising from spontaneous combustion, and effects other important advantages.

In the drawings, A denotes the main cardcylinder, and B the frame or a portion of the frame, of a carding-engine for carding-wool. O is the doffer-roller or cylinder.

Underneath the card-cylinderA an endless apron or grid D is arranged, as shown bythe drawings, the upper part of the said apron or grid being tangential or thereabout to the cylinder. This apron or grid runs around three rollers E F G, the middle one (viz., F) having its journals upheld by boxes or standards G G, such being provided with adjusting-screws and slots, (seen tt b 0,) by which such roller may be raised or lowered and fixed in its position with reference to the The said roller F is a supporter of the endless apron or grid when the latter is nearest to the main card-cylinder. I prefer a roller rather than a bar on account of the diminution of friction which results from the use of the roller. A bar, however, provided with adjustments may be substituted for the roller and be considered as an equivalent therefor so far as supporting the apron or grid and regulating its distance from the card-cylinder are concerned.

A pulley CZ is fixed on the shaft of the roller E and carries a crossed endless band e, which also extends around a driving-pulley f, fixed on the shaft of the main card-cylinder. While the latter is in revolution in the direction denoted by the arrow h (see Fig. 2) the apron or grid will be moved in the direction represented by the arrow i of such igure.

e eem/e If the part- D be Va common apron of cloth or leather, it will discharge the dirt from its upper end; but when made of a series of bars k la k, arranged parallel to each other and fixed at their ends to two endless belts ZZ, much of the dirt which may fall from the main cardbylinder will drop through the intelstices or spaces between the said bars, the brous material or Waste being received on the bars and subsequently carried up by them into such close proximity with the cardcylinder as to be seized thereby and again subjected to the action of the @aiding-rollers.

In carrying out my invention the arrange-- ment of the endless apron or` grid With respeet to the main card-cylinder should be such as to have such apron below the cylinder, and so as to enable the apron to operate properly in catching the Waste and restoring it to the cylinder. f.

main card-cylinder, I olairn the arrangement and combination of an adjustable supporter F, the same being to operate in manner and for the purposes substantially as hereinbefore set forth.
